Striped rice borer sex pheromone composition and inducement core thereof

Abstract

The invention provides a striped rice borer sex pheromone composition and an inducement core thereof. The striped rice borer sex pheromone composition is characterized by mainly comprising the components of Z11-hexadecenal, cis-13-octadecatrienal, Z9-hexadecenal and 16-C-aldehyde according to the weight ratio of 48:0-20:5-100:1-100; the sex pheromone composition is added into a releaser, and the releaser is used as a sustained-release material which is any one of natural rubber, synthetic rubber, polyethylene, polyvinyl chloride, a paper material, resin or a viscose material capable of being slowly and evenly released; and the formulation of a striped rice borer synthetic sex pheromone with high inducement effect is obtained through a large number of field test screenings and optimizations, and the new proportion shows the characteristics of large trapping capacity, stable inducement effect and the like in the field. The striped rice borer sex pheromone composition has simple and safe operations and low cost, can be applied to the forecast and the prevention and treatment of striped rice borers, and has great social, economic and ecological benefits.

Description

technical field [0001] The invention relates to a new formulation of the sex pheromone of the stem borer and the field of application equipment thereof. Background technique [0002] Chilo borer is distributed in various rice regions in southern and northern my country. Host plants include rice, corn, sugarcane, millet, broad bean, wild rice stem, sorghum, wheat, etc. In recent years, the insect has caused serious damage to rice and wild rice in some areas. [0003] Semiochemicals are a general term for compounds that play a role in chemical communication between organisms, and are the chemical molecular language used by insects to communicate. In nature, after sexual maturity, female adults of Chilo suppressalis release a compound called sex pheromone, which is released into the air and diffuses with the airflow, stimulating the chemical sensory organs in the antennae of males, causing sexual impulses in males And lure the male insects to fly to the release source, and m...

AI Technical Summary

Problems solved by technology

However, a large number of field experiments and applications have found that the trapping effect of the lure made with this ratio is not ideal, especially when the population density in the field is low, it is difficult to trap male moths

In addition, the two main components of the sex pheromone of the rice stem borer are the same as those of the rice stem borer, so the lures made in this way often trap the stem borer in the field, which is not conducive to forecasting, and the control and trapping effect is not ideal

Although some are formulated as lure cores that can simultaneously attract the two stem borers and the three stem borers, due to the unsatisfactory ratio, the effect of attracting the two stem borers is affected at the same time.
